15 Claims. (01. 2 42124) This invention relates to a beam moreparticularly a yarn beam such as used for warp threads and has for itsobject to provide for an adjustment or axial movement of the head memberwith reference to the body member.

Another object of the invention is the provision of a means wherebysmall adjustments of the head member on the body member may be obtainedby relative rotation of the members when at substantially'the desiredlocation.

Another object of the invention is the provision of a means wherebysmall adjustments of the head member on the body member may be obtainedby relative rotation of the members and large adjustments by disengagingand sliding the head member along the body member.

A further object of the invention is a provision of means whereby thehead may be clamped in desired position along the body mem- W) ber.

A still further object of the invention is the simplification ofconstruction with the attendant advantageous results.

With these and other objects and advantageous features in view, theinvention consists of a novel arrangement of parts more fully disclosedin the detailed description following, in conjunction with theaccompanying drawings, and more particularly set forth in the appendedclaims.

In the use of beams for yarn such as warp beams or the like'it isfrequently desirable to adjust the heads of the beam to vary theeffective length of the beam for use in a loom where various widths offabric are to be woven. Fine ad justments are also desirable and yetwhere a large movement of the head along the bodyis desired somemeansfor quickly moving the beam head is desirable and in order toaccomplish these results, I have provided an adjustment member which maybe secured at diiferent places along the body of the beam and easilymoved to the different adjusted positions and which has threadedengagement with the head member for finer adjustments of the positon ofthe head member along the beam; and the following; is a detaileddescription of the present embodiment of this invention illustrating thepreferred means by which these advantageous results may be accomplished.

With reference to the drawings, 10 designates the body member of thebeam which is of generally cylindrical tubular form pressed inwardly toprovide a warp end securing channel 11, hav- 55 ing a bottom wall 12,and side walls 13 at right angles to the bottom wall 12. Threadedopenings 14 are provided in the bottom wall 12 and a block member 15 ofa length substantially the distance between the openings 14 is slidablealong the channel 11 and is provided with threads 16 projecting abovethe outer cylindrical surface 1'7 of the body member. An opening 18 isprovided through the block to receive a bolt 19 which has threadedengagement with the selected opening 14 in the bottom of the channel tohold the block in place.

The beamhead has a face portion 20 and a hub 21 with strengthening ribs22 of any desired number extending between the face portion 20 and thehub 21. This hub has an opening'to receive the body member which openingis threaded as at 23 to engage the threads'lfi of the block member 15whereby rotation of the beam head relative to the body member causesaxial movement of the head member along the body member. The hub 21 issplit as at 24 with its ends spaced and each end portion is providedwith a threaded car 25 and a non-threaded car 26. A bolt 27 extendsthrough the car 26 and has threaded engagement with the ear 25 wherebythe hub may be contracted in diameter to tightly grip the body memberand prevent relative rotation of the parts.

For small adjustments of the beam head relativeto the body member thebolt 27 is loosened and the head member rotated relative to the bodymember. For larger adjustments the head is rotated to a position toexpose the binding bolt 19 either by completely uncovering the same orby moving opening 28 in the hub to a position to register with the bolt19 whereby it may be withdrawn from opening 14 which it enterspermitting the block to be moved to a new position by sliding alonggroove 11 carrying the head with it to be clamped in place in theopening 14 in the bottom of the channel. After which the fineradjustment may be obtained by relative rotation and the binding bolt 27tightened. V In order to apply friction to retard the rotation of thebeam, a sheave 30 is mounted upon one end thereof and bolts 31 welded tothe inner surface of the body extend through openings 32 in the sheaveand are provided with nuts 33 to secure the same in place, while a pin34'having a squared end to fit into the channel is provided with arounded portion 35 extending into the sheave to prevent the sheave fromturning relative to the body member.

In some instances a modified form of beam is used as illustrated in Fig.6 in which the body has openings 36 for securing the warp threads inposition instead of the groove as heretofore mentioned with fillingstrip therein. In this construction a bar 3'7 extends along the innersurface of the tubular body 38 and threaded openings 39 are provided forthe reception of adjusting member 40 which has a fin 41 extending fromits head for engagement with the threaded groove 42 of the hub portion43 of the head 44 which hub 43' is split and provided with ears 45 and abinding member 46 in a'manner similar to that heretofore mentionedfi Inthis modification the sheave is also differently mounted in that asleeve 47 is secured within the end of the body and provided withan-inwardly extending bearing 48 to receive the shaft 49 extendingthrough the sheave 50 and into the bearing 48. The sheave 50 is securedto this sleeve by suitable bolts 51 having threaded engagement with thesleeve as illustrated in Fig. 6. The sleeve is recessed as at 52 toreceive the bar 37 which is suitably secured by welding or the like tothe inner surface of the body.
